Case 446 Parts Catalog – OEM Factory Parts for Your Compact Tractor

You’ve got a Case 446 in the shop, serial number 9742953 or later, and you’re staring at a broken bracket or a leaking engine seal. The local dealer tells you a part number, but you want to verify it yourself. That’s where a factory parts catalog earns its keep. This Case 446 Parts Catalog runs 41 pages with exploded diagrams and part numbers that match the original build. No aftermarket reinterpretation. No “fits similar models.” The grid coordinates let you pinpoint exactly which bolt goes where.

Case 446 Parts Catalog: Engine and Tractor Sections

The ENGINE SECTION starts on page 5 with the air filter assembly – grid A6. Carburetor, fuel system, and governor components are listed there too. The BASIC TRACTOR SECTION begins on page 29 – frame and grille assembly, grid C2. Need a crankshaft? The alphabetical index directs you to the engine section grid. Every assembly from front axle to rear wheels has its own two-page spread with reference numbers that tie to the part list.

Page 5 is your starting point for engine parts. Page 29 for the chassis.

Use the Alphabetical Index First

Before you flip through 41 pages randomly, go to the alphabetical index on the first page. It lists every assembly – from Air Filter to Wheels – with the page number and grid coordinate. For example, “Brakes” points to page 37, grid C10. That grid system tells you where on the page the exploded view sits. Saves you from scanning the whole page.

That grid coordinate is the difference between a five-minute part lookup and a twenty-minute headache.

Why OEM Parts Catalogs Beat Third-Party Cross-References

I have seen aftermarket catalogs list a part that is “close enough” but not exact. The thread pitch is different, the bolt length is off, or the hydraulic fitting has a different flare angle. This Case 446 Parts Catalog comes from the factory. The part numbers in the numerical index at the back match the engineering release. When you order using these numbers and specify your machine serial number, you get the correct piece. The manual also includes an “Indented Description” – sub-assemblies are indented under the main assembly, so you know which pieces belong together. OEM documentation practices follow guidelines recognized across the Automotive Industry Overview and heavy equipment sectors. Serial number tracking is standard in the Automotive Industry Overview to ensure correct parts.

Updates and Changes: Why You Need the Latest Revision

The catalog explains that when Case makes changes, revised pages are issued with the same page number but a new issue date. The instruction says: “It is imperative that revised Parts Book pages be inserted into their respective Parts Books as soon as received.” If you are using a scanned copy, make sure it includes all revisions. This copy from AutoRepairManuals is a complete factory scan, not a third-party reproduction.

What This Parts Catalog Does Not Include

This is a parts catalog – exploded views and part numbers. It does not contain repair procedures, torque specs, or diagnostic steps. You need a service manual for that. But when you have the parts catalog open alongside the service manual, you can identify the exact component before you disassemble. That eliminates confusion about which seal or gasket to order.

Does this catalog include torque specifications for engine bolts?

No.

How do I order parts using this catalog?

Locate the part in the exploded view, note the reference number, then find the corresponding part number in the list. The catalog includes a numerical index at the back that cross-references part numbers to pages. When ordering, provide the part number, full description, quantity, machine model and serial number, and engine model and serial number. This ensures you get the correct genuine Case part. The catalog specifies that orders should also include method of shipment and shipping address. Missing any of this information can result in wrong parts or delays. Using the factory catalog eliminates guesswork because every part is tied to the original design specification.

If you work on Case 446 tractors, having the factory parts catalog on hand is not optional – it’s the difference between ordering exactly what you need and gambling with cross-reference lists. Access the Factory Manual and keep it in your shop’s digital library.
